I wish I knew the answer. I watched several hours of After Effect tutorials, but still am not very comfortable with it, so I'm still frame-by-framing it with PS. I've got an idea in mind that's going to require video in video so I guess I'm going to have to watch a few more videos.

Notorious GOP is the man to answer that. Also, there's a big collection of tutorial videos on a website called Creative Cow if you have some time to burn.

Yea. I've used a lot of different programs for a lot of different things, and AE is easily the most daunting to learn. If you want to check and see if you have Mocha, look under the Animation tab, about 6 options up from the bottom.

What is even better is you can go to your favorite torrent site and download Mocha Pro. It has many more features than the regular Mocha for AE that comes bundled. Once you have this go into preferences and tick "Use this version with AE" and Pro will fire up when you pick track in Mocha from the After Effects animation tab.
